Abstract
Description
図1は、第1実施形態にかかる過酸化水素生成装置10の全体構成図である。過酸化水素生成装置10は、電解槽12と、電極14と、電極16と、貯留タンク18と、原水ポンプ20と、循環ポンプ22と、バルブ26、28と、配管30、32、34、36、38、40とを備えている。配管30、配管34及び配管38は、循環配管の一例である。
(陰極) 4H2O+4e−+O2→2H2O+4OH− ・・・(第1反応)
(陽極) 2H2O→O2+4H++4e− ・・・(第2反応)
更に、電極14側で発生したOH−ラジカルによるH2Oの酸化により副次的に過酸化水素が生成される。
(陰極) Ca2++2e−→Ca ・・・(第3反応)
過酸化水素生成装置10では、電極14と電極16とを同じ材料及び同じ形状にした場合、定期的に電極14と電極16の極性を反転させることができる。即ち、電極16が直流電源90の負極に接続され、電極14が直流電源90の正極に接続される。これにより、電極16が陰極となり、電極14が陽極となる。過酸化水素生成装置10は、第4反応に示すように、陰極として機能していた電極14上に析出していたカルシウム等の無機イオンを電解液80に溶解させて、当該電解液80とともに外部へと排出する。この後、陽極として機能する電極14は第2反応を進めて酸素を発生させ、陰極として機能する電極16は第1反応を起こす。これにより、過酸化水素生成装置10は、陰極から陽極に反転させた電極14を再生して寿命を延ばしつつ、上述の反応を進めることができる。
(陽極:極性反転直後) Ca→Ca2++2e− ・・・(第4反応)
図2は、第2実施形態にかかる過酸化水素生成装置110の全体構成図である。過酸化水素生成装置110は、電解槽12と、電極14と、電極16と、気液分離タンク118と、原水ポンプ120と、コンプレッサー122と、バルブ126、128と、配管130、132、134、136、138、140と、散気管142とを備えている。配管130、配管134及び配管138が、循環配管の一例である。
実験の条件は、以下のとおりである。
電極に印加される直流電源の電圧:10V
電極に流れる電流:100mA
通電時間:60分
電解液:水道水
